The Verdict
Infisical is built for development teams and devops engineers, with a focus on secret-management and env-sync. Kong targets platform engineers and microservices teams and leads with api-gateway and service-mesh.
On pricing, Kong is the clear winner for budget-conscious users — starting at $0.05/mo compared to $6/mo for Infisical. That $5.95/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Kong offers broader built-in capabilities (8 features vs 7), while Infisical takes a more focused approach — which can mean a simpler, faster onboarding experience.
